R. White. What is Spatial History? Spatial History Lab: Working paper; Submitted 1 February 2010;
Paragraph 36 (emphasis author): “One of the important points that I want to make about visualizations, spatial relations, and spatial history is something that I did not fully understand until I started doing this work and which I have had a hard time communicating fully to my colleagues: visualization and spatial history are not about producing illustrations or maps to communicate things that you have discovered by other means. It is a means of doing research; it generates questions that might otherwise go unasked, it reveals historical relations that might otherwise go unnoticed, and it undermines, or substantiates, stories upon which we build our own versions of the past.”

With many thanks to Katie Anderson of NYU Libaries Data Services who is in no way responsible for my (mis?)use of her work.
Who should know how to do this?
#generate distances of all amphitheaters to all other amphitheaters
ramphs.dists <- spDists(ramphs.sp,ramphs.sp,longlat = TRUE)
# but let's use names
colnames(ramphs.dists) <- ramphs$id
rownames(ramphs.dists) <- ramphs$id
# Would be nice to have a d.f in the form from,to,km
as.data.frame(ramphs.dists) -> ramphs.dists.df
#add column of names, in anticipation of using gather()
cbind(from = ramphs$id,ramphs.dists.df) -> ramphs.dists.df
gather(ramphs.dists.df, to, km, 2:dim(ramphs.dists.df)[2]) -> ramphs.dists.df
# data now in nice columns but...
# we still have the 0Km rows.
#set phasers to kill...
ramphs.dists.df[ramphs.dists.df$km > 0,] -> ramphs.dists.df
